The ultrasonic transmitters emit a quantity of energy into the water that is sufficient to make gas bubbles between the water molecules. These bubbles are inflated in a number of pressure changes of the transmitter.
At a critical size, these bubbles will implode and cause a pressure of 2000 atmospheres. This pressure wave runs into the water at a speed of about 1250 meters per second.
If this pressure wave encounters a micro-organism, for example a bacterium, the membrane will tear because of the rapid pressure changes. After that the inner DNA comes to the turn. This is the end of the bacterium.
The unique thing about the USAF transmitters is that these transmitters are placed directly in the seawater. This allows them to deliver maximum power to the water, resulting in maximum cavitation.
The effectiveness depends on this cavitation.
The quantity of cavitation produced is decisive for the quality of the transmitters.
The amount of cavitation bubbles is visible on a video of one of our channels.
